But now alien enthusiasts have waded in after seeing something strange appear on NASA’s live feed of the event.

In footage taken from the famous Griffith Observatory in Los Angeles, US, a white object flies past the surface moon.

At its tail, a light appears to flash.

The witness who spotted the moment said: “I just happened to notice an object travelling at a very high rate of speed going down the left side of the moon and downwards to the left until it was out of the frame.
